AI Technical Summary

Benefits of technology

The invention is about a process for producing a charcoal ignition fluid using a renewable feedstock. The process involves hydrotreating the feedstock with a C4-24 isoparaffinic diluent to produce an n-paraffinic fraction, which is then hydroisomerized to produce an isoparaffinic blend. The isoparaffinic blend is then fractionated by boiling point to produce the charcoal ignition fluid with specific characteristics. The resulting fluid contains a high amount of linear and branched C7-18-alkanes, and may also include other components like paraffin, naphthalene, and sulfur compounds. The process is carried out at specific conditions and can use a sulfide bimetallic catalyst. The resulting fluid has specific physical properties like viscosity, flash point, density, auto-ignition temperature, vapor pressure, boiling point, and freezing point. The fluid is non-toxic and free of aromatic compounds and sulfur compounds.

Problems solved by technology

The petroleum-based charcoal starter fluid that is most widely in use is a petroleum distillate that contains significant levels of aromatic and sulfur-containing compounds, which may affect the quality and safety of food cooked over charcoal ignited with this fluid.
Additionally, the petroleum distillate charcoal starter fluids consume a significant quantity of petroleum, a non-renewable fossil fuel.
Charcoal starter fluids incorporating petroleum distillates currently in use have a number of drawbacks relative to consumer and environmental issues.
For example, they contain a significant and potentially toxic amount of aromatic compounds.
Consumers who do not wait until these toxic compounds burn off adequately before placing food over charcoal ignited with petroleum distillates may unknowingly contaminate the food with residues from the incomplete combustion of the fluid still contained in the charcoal.
Charcoal starter fluids with flashpoints higher than 110° F. are typically too difficult to be ignited, and are therefore, not accepted by consumers.

example 1

[0050]The process by which animal fats are converted to normal paraffins is described in U.S. Pat. No. 7,846,323 entitled “Process for Co-Producing Jet Fuel and LPG from Renewable Resources,” issued to Syntroleum Corporation (Tulsa, Okla.), which is expressly incorporated herein in its entirety. The renewable feedstock is placed in a reactor and converted to n-paraffins using a hydrotreating process with a nickel-molybdenum as a catalyst. Based on the cloud point of the resulting hydrocarbon liquid, a portion is then hydroisomerized to produce an isoparaffinic product that, when blended properly with the normal paraffin, can be fractionated to the proper boiling range for the charcoal ignition fluid detailed in Table 1 above. The carbon number distribution would be C6-C18 for paraffinic alkanes derived from this raw material using this particular Fisher-Tropsch process.

example 2

[0051]The same process described in Example 1 is modified such that the normal paraffin resulting from the initial hydrotreating stage is fractionated before being blended with the isoparaffin resulting from the hydroisomerization step, which can be fractionated separately. In this example, the cloud point of the final product can be determined without the need to make adjustments after fractionation.

example 3

[0052]A test was conducted with the charcoal ignition fluid and an odorless kerosene ignition fluid used as a control. The test involved decanting 100 ml of ignition fluid onto twenty-four (24) charcoal briquettes stacked in the same manner for both the test of the charcoal ignition fluid and the control. This test was conducted on three (3) separate occasions when the air temperature was 40° F., 74° F. and 107° F. In each test, the time was measured from the point of ignition until the charcoal was considered adequately ignited to begin cooking. In each case, the performance of the charcoal ignition fluid was equal to or better than that of the kerosene ignition fluid.

[0053]Whereas, the compounds and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.

Abstract

A charcoal ignition fluid that is composed of a blend of bio-based hydrocarbons for the ignition of charcoal in both briquette and lump forms. The charcoal ignition fluid utilizes linear and branched alkanes produced by means of variations of the Fischer-Tropsch process that incorporates raw materials that are generally recognized as more sustainable than petroleum oil. The process for producing the charcoal ignition fluid deoxygenates fatty acids, esters, etc. by removing and fully saturating all double bonds in the bioactive raw materials.
